    Abstract

    Incorporation of Paclitaxel in Mesenchymal Stem Cells Using Nanoengineering Upregulates Antioxidant Response, CXCR4 Expression and Enhances Tumor Homing

    Loading paclitaxel in MSCs resulted in increased levels of mitochondrial reactive oxygen species. In response to this oxidative stress, MSCs upregulated two important set of proteins.

    Ultrasound-Derived Mechanical Stimulation of Cell-Laden Collagen Hydrogels for Bone Repair

    Bone marrow-derived stromal cells were encapsulated in type I collagen hydrogels and mechanically stimulated using low intensity pulsed ultrasound-derived acoustic radiation force.
    [Journal Of Biomedical Materials Research Part A]

    Abstract

    Increased PRL-1 in Bone Marrow-Derived Mesenchymal Stem Cells Triggers Anaerobic Metabolism via Mitochondria in a Cholestatic Rat Model

    Compared to naïve cells, bone marrow-MSCs phosphatase of regenerating liver-1 (PRL-1) showed an improved antioxidant capacity and mitochondrial dynamics, as well as decreased cellular senescence.

    Human Dental Pulp Stem Cells Ameliorate the Imiquimod-Induced Psoriasis in Mice

    Scientists determined the effect of human dental pulp stem cell on the imiquimod-induced psoriasis in mice. The psoriasis model was established by topical application of imiquimod cream in mice for seven days.
